任何人都可以建议一种方法来清理这个凌乱的classname结构:
const ButtonTemplate = props => {
const themed = `btn-${props.theme}`
const themedButton = `${styles[themed]} ${themed}${(props.disabled) ? ' disabled' : ''}}`
return (
<button className={`${styles.btn} ${themedButton}`} type='button' onClick={props.onClick}>{props.children}</button>
)
}

怎么样?
function ButtonTemplate({theme, disabled, onClick, children}) {
const themed = `btn-${theme}`;
return (
<button className={[
styles.btn,
styles[themed],
themed,
disabled ? 'disabled' : ''
].join(" ")} type='button' onClick={onClick}>{children}</button>
);
}

使用包classnames:
安装:
npm install classnames
导入:
import classNames from 'classnames';
使用它:)
const ButtonTemplate = props => {
const themed = classNames('btn-', props.theme)
const themedButton = classNames(
styles.btn,
styles[themed],
themed,
{ disabled: props.disabled }
);
return (
<button className={themedButton} type='button' onClick={props.onClick}>{props.children}</button>
)
}
这可能非常有用,因为我们将在开发一个大项目时面临类似的情况。以下是从original documentation复制的一些技巧:
classNames('foo', 'bar'); // => 'foo bar'
classNames('foo', { bar: true }); // => 'foo bar'
classNames({ 'foo-bar': true }); // => 'foo-bar'
classNames({ 'foo-bar': false }); // => ''
classNames({ foo: true }, { bar: true }); // => 'foo bar'
classNames({ foo: true, bar: true }); // => 'foo bar'
// lots of arguments of various types
classNames('foo', { bar: true, duck: false }, 'baz', { quux: true }); // => 'foo bar baz quux'
// other falsy values are just ignored
classNames(null, false, 'bar', undefined, 0, 1, { baz: null }, ''); // => 'bar 1'
......还有更多。你应该看看它并尝试一下。

const ButtonTemplate = props => {
const { children, disabled, onClick, theme } = props;
const disabled = disabled ? 'disabled' : '';
const themed = `btn-${theme}`
const className = `${styles.btn} ${styles[themed]} ${themed} ${disabled}`;
return (
<button className={className} type='button' onClick={onClick}>{children}</button>
)
}
